摘　　要：在自来水供水系统中,以光伏发电系统作为水塔的供电系统,采用推挽正激式电路将光伏阵列发出的直流低压电进行升压,经过三相桥式逆变电路后,输出三相交流电压。在该系统中,特别提出了由单片机根据传感器发出的水塔水位信号,指令电磁开关的断开与闭合,从而控制交流异步电机带动水泵向塔供水。. In the tap water supply system, which the photovoltaic power generation system supplys as the power of water tower, we use the push-pull forward circuit to boost the low DC voltage from photovoltaic array. Through three- phase bridge inverter, the output gives three-phase AC voltage. In this system, we especially put forward the method for o- pening and closing of the water pump controlled by single chip Microcomputer （SCM） according to the sensor signal of wa- ter tower level, thereby controls the AC asynchronous motor to drive the water pump to supply the water.
